To dZZ whorl z it may cone era;

Be it known that I, PETER NICOLAUS KROG; MANN, a subject of .the'Emp'eror of Germany,'- residing at New York, (Brooklyu,) in J the county of 'Kings and State of New York, have invented certain new and useful Improvementsin Account-Books, of which the fol-. lowing is a full and complete specification,

such as will enable those skilled in the art to which it appertains to make and use the same, i

This invention 7 relates to. accounbbooks'; and the object thereof is to provide books of this class with improved mechanical features whereby the classification of commercial-and other papers may be more easily accom- ,plished.

My invention-is fully disclosed in the folilowing specification, of which the accompanying drawings form a part, in which like reference characters denote like parts in Figure 1 is a plan view of an open book provided with my features of improved con-j struction, the corresponding corners of a part of the leayes' being turned forwardly to ex pose oneof saidfeatures; and Fig. 2, a seean entrybookfor order-book in which are recorded-the purchases of their'various customers, and at 4 the leaves thereof, upon which are arranged the ordinary entry-lines 5 and column-lines 6. Each of the leaves 5 is cut away at its outer side edge, as at 7, each leaf beginning at the back of the book being cut away to a predetermined greater extent than its predecessor, and by means of this;

formation flaps 8 are formed, and these flaps are of the ordinary construction in page-index} These flaps 8 are ordinarily provided:

books. with printed or written index characters upon their front faces but according to my inven-:' tion I provide each flap 8 with a detachable card or label 9, upon which 'may be written any index characters desired, and the cards 9 are each secured in place by means of a spring-clip 10, each of which preferably consists of a square single piece of spring-wire, which is bent into a frame-shaped front portion 11, the ends being formed into diverging rear portions l2.

Fig. 2 andin dotte and full lines in Fig 1.) The rear portions 2 are passed behind the flaps 8, and the front portions 11 are passed in front of the cards 9,'securely binding them against the flaps 8, as is shown in Fig. 2. The

the" several'views, and in which- (Shown in full lines iii peculiar ang la frame shape of the front portion 11 of the clips 10 is particularly adapted to the end in view, as the symbols upon the cards Qare readily discernible there 7 Upon each. leaf provided with o'ne of the cards 9 and clips 10 is arranged a transverse 'keeper 13-, consisting, preferably, of a slip or band of paper secured at its ends, as at 14, to Beneath the keeper 13 may be placed a plurality of bill-heads or copies of orders or other papers which it is desired to classify according to thecorresponding card 9. By means of this keeper each page'may accommodate a largeamount of data and numerous items of sale, &c., far in excess of what the surfaoeof thepage itself would accommodate.

Arranged upon the inner surface of one or passed about the clip 15 and through the cover 3. This supplemental clip 15 may be employed to hold sundry papers and memorandum-sheets which findl no place among the indexed pages. 4 g

It is evident that by means of the cards 9, the clips 10 and 15, and keeper 13 an account or other book may be caused to accommodate a large number of classified papers, the data of which may exceed many times that which the unaugmented pages of the book would accommodate, and that the cards "Qfmay be readily interchanged and supplanted by fresh cards as desired.

It is evident that many changes may be made in the adaptation, arrangement, and construction of the features of my invention without departing from the spirit thereof or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- An improved book, comprising a leaf, an

- card upon said leaf, comprising a single length index-card connected with the edge thereof, and means for d etachably securing said indexof wire formed into a square frame-shaped portion between which, and the face of the leaf, said index-card is clamped, the ends of said single length of wire being passed di- Vergently beneath said leaf and directly behindsaid frame-shaped portion, the construction of said frame-shaped portion and the relative arrangement thereof and of said index-card being such, that said frame-shaped portion impinges upon said card in the marginal portions. thereof, whereby the legend of said card is readily and unimpairedly' discernible therethrough.

' In testimony that I claim the foregoing as my invention I have signed my name, in presenceof the subscribing witnesses, this 12th day of July, 1899.
